getenv() problem (getting ip address)

[madcat]

Hi-

Why would this not produce an IP address:

$ip = getenv("REMOTE_ADDR");
echo $ip;

I have to instead use:

$ip = $_SERVER['REMOTE_ADDR'];
echo $ip;

--> PHP.NET and the author of my book talk about the first method. Any reasons or ideas are appreciated.

<?=$REMOTE_ADDR;?>

What?

[Mark]

$ip = getenv("$REMOTE_ADDR");
echo $ip;

you forgot the $ infront of REMOTE_ADDR

thanks- but that's unfortunately not it. This example is from PHP Fast & Easy Web Dev. and php.net as well. This is a local server using Apache on Windows XP- I don't know if this has anything to do with why it's not working- doubtful though.

k well anyways if you want to show an ip address, just use
<?=$REMOTE_ADDR;?>
